前言
本教程使用的是三维激光雷达为北科天绘的R-Fans-16,采用网口连接传输数据，9-36V供电。
Ubuntu版本为20.04，Ros版本为Neotic。
二、ROS Driver
1.创建工作空间并初始化
mkdir -p /ros_ws/src
cd /ros_ws/src
catkin_init_workspace
将ROS-Driver_vX.X.X.zip 解压得到 ROS-Driver_vX.X.X 文件夹，将该文件夹下的 ROSDriver文件夹复制到 /ros_ws/src目录下。
ROS-Driver功能包
修改ros_ws/src/ROSDriver/launch目录下的node_manager launch文件
需要修改DateGrade为4.0_format, model为R-Fans-16（根据雷达型号），frame_id 为 world

sudo apt-get install libpcap-dev //安装依赖的 libpcap 库:
cd ~ /ros_ws//编译
catkin_make
2.启动雷达驱动程序
cd ~/ros_ws
source devel/setup.bash
roslaunch rfans_driver node_manager.launch//运行 ROSDriver:
三、 RVIZ 显示 R-Fans 点云数据
启动 rviz
新开终端:rviz
加载 rviz 配置文件:点击 rviz 菜单栏 File 选项中的 Open Config 按钮(ctrl+O),
加载 ros_ws/src/ROSDriver 下的 RFans_Rviz_cfg.rviz
